Hey everybody. I would like to let you know i have "fixed" it. Now i have the disklabel layout i want. I managed to get it working because instead of using 512/4K fragment/block size (using disklabel into expert mode) i tried with 1K/8K for the a partition.
Now it works. Although i have no ideia how block size could influence that. Would someone mind commenting it, i.e., why i could not use 512/4K for frag/blk size? thanks. PS: Good work for 3.7, just now i have it installed in my box.
